FlavScents AInsights Entry for Fucus Vesiculosus Extract (CAS: 84696-13-9)

1. Identity & Chemical Information

Fucus vesiculosus extract, commonly known as bladderwrack extract, is a natural complex material derived from the brown seaweed Fucus vesiculosus. This extract is not a single chemical compound but a mixture of various constituents. The CAS number for this extract is 84696-13-9. It does not have a specific FEMA number or IUPAC name due to its complex nature. Other identifiers such as FL number, CoE number, or IFRA reference are not typically assigned to such extracts. The composition of fucus vesiculosus extract can vary significantly depending on the source, harvest time, and processing methods.

2. Sensory Profile

Fucus vesiculosus extract is known for its marine-like, seaweed odor, which can be described as briny and slightly earthy. The intensity of the odor is moderate, and it is often used to impart a natural marine note in fragrance compositions. The extract does not have a significant taste profile and is primarily used for its olfactory properties. It serves as a background realism note in formulations, enhancing the authenticity of marine-themed scents.

3. Natural Occurrence & Formation

Fucus vesiculosus is a type of brown seaweed found in the Atlantic and Pacific Oceans, as well as the North and Baltic Seas. The extract is obtained through processes such as solvent extraction or steam distillation. It is considered a natural ingredient in both flavor and fragrance applications due to its direct derivation from a natural source. The extract's composition can include polysaccharides, phenolic compounds, and iodine, among other constituents.

4. Use in Flavors

Fucus vesiculosus extract is not commonly used in flavor applications due to its strong marine odor, which can be overpowering in food products. However, it may be used in very low concentrations to provide a subtle marine note in certain savory or seafood-flavored products. Typical use levels in finished food or beverage products are not well-documented, but industry estimates suggest usage in the low ppm range. The extract is relatively stable under normal food processing conditions but may degrade under extreme heat or acidic conditions.

5. Use in Fragrances

In the fragrance industry, fucus vesiculosus extract is valued for its ability to impart a natural marine character to compositions. It is used in fragrance families such as aquatic, oceanic, and fougère. The extract acts as a background realism note, enhancing the authenticity of marine-themed scents. Typical concentration ranges in fragrance formulations are qualitative, with the extract often used in trace amounts to avoid overpowering other notes. It contributes primarily to the middle notes of a fragrance due to its moderate volatility.

5a. Key Constituents (Typical)

Fucus vesiculosus extract typically contains polysaccharides such as alginates, phenolic compounds like phlorotannins, and minerals including iodine. The composition can vary based on factors such as geographic origin, harvest season, and extraction method. These constituents contribute to the extract's sensory and functional properties.

6. Regulatory Status (Regional Overview)

In the United States, fucus vesiculosus extract is not specifically listed as GRAS by FEMA for flavor use, but it may be used under general food additive regulations. In the European Union, it is subject to the regulations outlined in Reg. (EC) No 1334/2008, with its use in flavors and fragrances being evaluated on a case-by-case basis. The United Kingdom follows similar regulations post-Brexit. In Asia, regulatory status can vary, with countries like Japan and China having specific guidelines for seaweed-derived ingredients. In Latin America, countries such as Brazil and those in MERCOSUR may have their own regulatory frameworks for natural extracts.

7. Toxicology, Safety & Exposure Considerations

For oral exposure, the safety of fucus vesiculosus extract in flavor applications is generally considered acceptable at low levels, though specific ADI or MSDI values are not well-documented. Dermal exposure in fragrance use is generally safe, but potential for irritation or sensitization should be evaluated, particularly due to the presence of iodine. Inhalation exposure is minimal due to the low volatility of the extract. Overall, the risk profiles for food and fragrance applications are similar, with the primary concern being potential iodine content.

8. Practical Insights for Formulators

Fucus vesiculosus extract is valuable for its unique marine character, which can enhance the authenticity of oceanic and aquatic-themed products. It synergizes well with other marine and green notes. Formulators should be cautious of its strong odor, which can easily dominate a composition if overused. It is often under-utilized in flavor applications due to its intense aroma but can be effective in trace amounts.

9. Confidence & Data Quality Notes

The data on fucus vesiculosus extract is well-established in terms of its sensory profile and typical constituents. However, specific regulatory approvals and safety data may be less documented, requiring formulators to rely on industry practices and general guidelines. Known data gaps include precise usage levels in flavors and comprehensive toxicological evaluations.

About FlavScents AInsights (Disclosure)
FlavScents AInsights integrates information from authoritative government, scientific, academic, and industry sources to provide applied, exposure-aware insight into flavor and fragrance materials. Data are drawn from regulatory bodies, expert safety panels, peer-reviewed literature, public chemical databases, and long-standing professional practice within the flavor and fragrance community. Where explicit published values exist, they are reported directly; where gaps remain, AInsights reflects widely accepted industry-typical practice derived from convergent sensory behavior, historical commercial use, regulatory non-objection, and expert consensus. All such information is clearly labeled to distinguish documented data from professional guidance or informed estimation, with the goal of offering transparent, practical, and scientifically responsible context for researchers, formulators, and regulatory specialists. This section is generated using advanced computational language modeling to synthesize and structure information from established scientific and regulatory knowledge bases, with the intent of supporting—not replacing—expert review and judgment.
